I turn a messy CSV or Excel file into a clean, structured dataset that is easier to use, analyse or import.

Typical fixes include duplicate records merged on a key you choose

Inconsistent dates, casing and text formatting

Missing or malformed values

Column cleanup and standardisation

CSV and Excel restructuring

You get the cleaned file, plus a short summary of what changed and a separate list of any records that need your decision. I never guess a value to fill a gap.

What I need from you: the source file, the output format you want, and any rules that must be preserved.

Scope: up to roughly 5,000 rows in this package. Larger or more complex files are quoted separately before we start.
